TECHNICAL FIELD

Exemplary embodiments of the present invention relate generally to systems and methods for measuring power consumption of electronic display assemblies.

BACKGROUND AND SUMMARY OF THE INVENTION

Electric meters have long been a staple of the home. These meters are typically located on or near the side of the house where the electric line connecting the home to the electrical grid enters the home. The electric meter is interposed at the entry into the home to determine the amount of power consumed by the home so that the owner may be billed based upon the actual usage. The same is generally true of other types of buildings (e.g., commercial).

Electronic displays are increasingly being used in both indoor and outdoor applications. Such electronic displays are sometimes placed in assemblies with a ruggedized housing in order to fit the intended application of the electronic display. Such applications include, but are not limited to, placement on city sidewalks, the sides of buildings, bus shelters, the tops of vehicles, billboards, entrances, stadiums, malls, airports, public transportation areas, and the like. Consumers have increasingly begun demanding larger, brighter, clearer displays, and the like. Consumers have also increasingly begun demanding more features associated with the electronic displays. Examples of such associated features include, but are not limited to, video conferencing, telephonic systems, internet connectivity, cameras, sensors, wayfinding, and the like. The result of these larger displays and added features is greater power consumption by the assembly.

In many cases, one party owns the assembly itself or the physical real estate (e.g., bus stop, sidewalk, building, entrance, signage, or the like) where the assembly is located. In many cases, this owning party is responsible for payment of the assembly's power consumption. However, in some cases it would be desirable to charge another party for the power consumption of the assembly—such as the party showing images on the display. For example, without limitation, in some cases, a city is responsible for the power consumption of such assemblies located on its sidewalks. However, it would be desirable to charge the owner of the assemblies for their power consumption. As another example, without limitation, in some cases, one party owns the display but rents out advertising time on the display to third parties. In such cases, it may be desirable to charge the particular advertiser for power consumed by the assembly while the third party's advertisement is being shown on the assembly.

In such cases, the party responsible for the assembly's power consumption might be forced to interject a power meter on or near the assembly to measure its power consumption. However, this is costly, labor intensive, unaesthetic, and takes up valuable real estate. Therefore, what is needed is an assembly for an electronic display having a simulated electric meter.

The present invention is an assembly for an electronic display having a simulated electric meter. The assembly may comprise a housing for one or more electronic display subassemblies. Each electronic display subassembly may comprise an illumination device, a display layer, and a cover. In exemplary embodiments, a closed loop of air may pass between the display layer and the cover of each subassembly and into a compartment located between the subassemblies. An open loop of ambient air may pass through each subassembly and may pass along the rear surface of the illumination device located therein. A number of electronic components for operating the assembly may be located in the compartment. The simulated electric meter may be in electrical connection with a utility electric supply and all of the electricity consuming components of the assembly such that all electricity consumed by the assembly may pass through the simulated electric meter.

The simulated electric meter may comprise a processor, an electronic storage device, a timing device, a current sensor, and a voltage sensor. The electronic storage device may comprise software instructions, which when executed, cause the processor to take measurements from the sensors. In exemplary embodiments, the sensors may determine the current and the voltage of the incoming electricity, which may be multiplied together to determine the power being consumed. In other exemplary embodiments, the voltage may already be known and multiplied with the current reading to determine power consumption. Such readings and power consumption calculations may be repeated over a period of time at a given frequency. The elapsed time may be measured by the timing device. After a predetermined amount of time has passed, the power measurements may be summed and divided by the total number of readings to determine an average consumption measure for the given period of time.

The simulated electric meter may be in electronic communication with a remote electronic device to monitor power consumption as well as review past power consumption and predict future power consumption. Additionally, the simulated electric meter may be in communication with the video player or a proof of play device in order to track what images are shown on the electronic display subassemblies of the assembly when the power is consumed.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details such as detailed configuration and components are merely provided to assist the overall understanding of these embodiments of the present invention. Therefore, it should be apparent to those skilled in the art that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

FIG. 1 is a perspective view of an exemplary assembly 10 for an electronic display comprising a simulated electric meter 44. The assembly 10 may comprise one or more electronic display subassemblies 12 located on a housing 14. In exemplary embodiments, a first and second electronic display subassembly 12 may be mounted to the housing 14 in a hinged fashion such that the electronic display subassemblies 12 are capable of being rotated between a closed position, wherein the electronic display subassembly 12 is in contact with the housing 14, and an opened position wherein the electronic display subassembly 12 is located away from the housing 14. One or more openings 16 may be located on or around the housing 14 such that ambient air 28 may be ingested into, or exhausted from, the assembly 10. The housing 14 may be configured to permit the assembly 10 to be mounted to a sidewalk, the ground, a building, a bus shelter, a vehicle, a wall, a billboard, in a window, in a storefront, or the like.

FIG. 2 is a perspective view of the assembly of FIG. 1 with some components removed and one of the electronic display subassemblies 12 in an open position so as to illustrate additional components of the assembly 10. In exemplary embodiments, the rear surfaces of the two electronic display subassemblies 12 and the housing 14 may define a compartment 15 located therebetween. The compartment 15 may be substantially sealed. Gaskets may extend along the perimeter of the housing 14 where the display subassemblies 12 meet the housing to provide such a seal. Various electronic components 18 may be mounted between or to one or more of the electronic display subassemblies 12 or to structures located within the compartment 15. Such electronic component 18 may be used to operate the assembly 10 and include, but are not limited to, video players, processors, electronic storage devices, camera, sensors, power sources, power modules, network connectivity devices, some combination thereof, or the like. Fans 22 may be located at various positions on the housing 14 or within the compartment 15 formed between the electronic display subassemblies 12.

FIG. 3 is a perspective view of the assembly of FIG. 2 with one of the electronic display subassemblies 12 located in an open position so as to illustrate additional components of the assembly 10. Assist devices 24 may extend between the housing 14 and the electronic display subassemblies 12 to assist in moving the electronic display subassemblies 12 between the opened and closed positions. These assist devices 24 may also assist in securing the electronic display subassemblies 12 in the opened or closed positions. The assist devices 24 may be gas springs, gas struts, pullies, levels, ratcheting devices, struts, members, springs, counter weights, cams, some combination thereof, or the like.

FIG. 4 is an exploded view of the assembly of FIG. 3 . Additional fans 22 may be located at various positions on the housing 14 or in the compartment 15. Additional equipment 42 may be located within the compartment 15. The additional equipment 42 may be various electronic and other components which facilitate the inclusion of additional features such as, but not limited to, video conferencing, telephonic systems, internet connectivity devices, cameras, and the like. For example, without limitation, the additional equipment 42 may comprise video players, processors, electronic storage devices, cameras, microphones, sensors, power sources, wayfinding equipment, power modules, network connectivity devices, some combination thereof, or the like.

FIG. 5 is a perspective view of the assembly of FIG. 2 with one of the electronic display assemblies 12 removed so as to illustrate additional components of the assembly 10. FIG. 6 is a top sectional view of the assembly of FIG. 5 . In particular, FIG. 5 and FIG. 6 illustrate an exemplary flow of ambient air 28 and circulating air 26 through the assembly 10. Ambient air 28 may enter from the ambient environment through the intake opening 16 and may pass through a gap 36 in one or more of the electronic display subassemblies 12. In exemplary embodiments, the gap 26 may be located such that ambient air 28 passes behind an illumination device 32 for an electronic display layer 31, though any located is contemplated. The illumination device 32 may be a backlight. In other exemplary embodiments, the ambient air 28 may instead pass through the compartment 15.

The electronic display layer 31 may be a liquid crystal display (“LCD”), Light Emitting Diode (“LED”), Organic LED (“OLED”), type display or the like. The illumination device 32 may comprise one or more incandescent light bulbs, LEDs, OLEDs, or the like. In exemplary embodiments, the illumination device 32 multiple light bulbs, LEDs, OLEDs, or the like, which may be arranged in an array on a sheet behind the electronic display layer 31 in a direct-lit arrangement, or adjacent thereto in an edge-lit arrangement, such as but not limited to, along the edge of a light guide located behind the display layer 31. In exemplary embodiments, a cover 34 may be located in front of the display layer 31. The cover 34 may be a transparent sheet, such as but not limited to, a cover glass.

In some exemplary embodiments, the electronic display layer 31 may transparent or translucent. The housing 14 may be configured to locate the electronic display layer 31 over a compartment, such as but not limited to, a cooler, vending machine, display case, or the like.

Ambient air 28 may exit the assembly 10 though the opening 16 where it is returned to the ambient environment. This pathway for the ambient air 28 may define an open loop. The ambient air 28 may be moved by one or more fans 22 placed along or near the open loop. One or more filtration devices may likewise be placed along the open loop. While the ambient air 28 is illustrated as traveling vertically from bottom to top, it is contemplated that the ambient air 28 may also travel vertically from top to bottom. Alternatively, or in addition, the ambient air 28 may travel horizontally.

Circulating air 26 may travel from the compartment 15 through one or more of the electronic display subassemblies 12. In exemplary embodiments, the circulating air 26 may travel through a channel 25 located between the cover 34 and the display layer 31. A similar pathway may be taken with a second flow of circulating air 26 within the second electronic display subassembly 12. Regardless, the circulating air 26 may be returned to the compartment 15. This pathway of the circulating air 26 may define a closed loop. The circulating air 26 may be moved by one or more fans 22 placed along the closed loop. While the circulating air 26 is illustrated as traveling horizontally, it is contemplated that alternatively, or in addition, the circulating air 26 may travel vertically. In exemplary embodiments, the open loop and the closed loop may be configured to substantially prevent the ambient air 28 and the circulating air 26 from mixing. In particular, the closed loop may be substantially sealed to prevent particulate in the ambient air 28 from mixing with the circulating air 26.

The illustrated open loop and closed loops are merely exemplary and are not intended to be limiting. Any pathway for ambient air 28 is contemplated. Likewise, any pathway for circulating gas 26 is contemplated. It is contemplated that in some embodiment, the closed loop and circulating gas 26 may not be required. In still other exemplary embodiments, the circulating gas 26 and closed loop may be limited to traveling within the compartment 15. It is similarly contemplated that in some embodiment, the open loop and ambient air 28 may not be required. Heat may be removed by the use of thermoelectric devices, air conditioning, fins, heat sinks, thermal plates, or the like.

As will be described in greater detail herein, the assembly 10 may additionally comprise a simulated electric meter 44. The simulated electric meter 44 may be located in the compartment 15 or on the housing 14, though any location on the assembly 10 is contemplated. The simulated electric meter 44 may be electrically connected to the electrical supply for the assembly 10.

In exemplary embodiments, the simulated electric meter 44 is located on, or in close proximity with, a connector 56. The connector 56 may be located on the housing 14 or other portion of the assembly 10 or the electrical display subassembly 12. In exemplary embodiments, the connector 56 is a pass-through device configured to permit one or more wires to pass through the housing 14 and into the assembly 10 while maintaining a substantially air-tight seal. The connector 56 may be configured to place the assembly 10 in electrical connection with a utility electric supply 54 by way or one or more utility electrical supply lines. The utility electric supply 54 may be an electrical grid, battery, generator, power plant, or the like. In exemplary embodiments, the connector 56 may serve as a connection point for the utility electrical supply line on one end and the simulated electric meter 44 (and thus the electricity consuming components of the assembly 10) on the other end. Any kind of connector 56 is contemplated including, but not limited to, an outlet, port, sealed passage, or the like. In exemplary embodiments, the connector 56 provides a substantially air tight seal so that the compartment 15 remains substantially sealed.

FIG. 7 is a simplified diagram illustrating an exemplary system utilizing the assembly 10. The simulated electric meter 44 may be in electrical connection with all of the electricity consuming components of the assembly 10, including but not limited to, the electronic components 18, the illumination device 32, the additional equipment 42, and a network connectivity device 46. In this way, the simulated electric meter 44 may be positioned to encounter all of the electricity flowing into the assembly 10.

FIG. 8 is a detailed view of the simulated electric meter 44 of FIG. 7 . The simulated electric meter 44 may comprise a processor 62, an electronic storage device 64, a timing device 66, a current sensor 68, and a voltage sensor 67. The simulated electric meter 44 may comprise other electrical components, including but not limited to, capacitors, resistors, relays, diodes, inductors, voltage sources, logic gates, microcontrollers, and the like. The current sensor 68 and the voltage sensor 67 may be in contact (direct or indirect) with the electrical wiring passing into or through the assembly 10. For example, without limitation, the simulated electric meter 44 may be located immediately adjacent to the connector 56, though any location is contemplated. While the current and voltage sensors, 68 and 67 respectively, are described as separate components herein, it is contemplated that a single sensor may be used to measure both current and voltage. Alternatively, or in addition, it is contemplated that the voltage may be a known, preprogramed value and only the current sensor 68 is required.

The current sensor 68 may be configured to detect the current of the electricity in contact therewith. Similarly, the voltage sensor 67 may be configured to detect the voltage of the electricity in contact therewith. The measured current and voltage values may be actual, approximate, peak, root mean square, average, median, mode values, or the like. Alternatively, or in addition, the voltage or current values may already be known and preprogrammed. For example, without limitation, the voltage of the supplied electricity may be known to be 120 v or 220 v.

As additionally shown in FIG. 9 , the electronic storage device 64 may comprise software instructions, which when executed, cause the processor 62 to take one or more readings from the current sensor 68 and the voltage sensor 67 for the electricity in contact with the current sensor 68 and the voltage sensor 67—that is, the electricity passing through the simulated electric meter 44 to be consumed by the assembly 10. In exemplary embodiments, such readings may be taken approximately once per second, though any frequency of readings is contemplated. The processor 62 may be configured to multiply the measured current value with the measured voltage value to determine a power consumption reading. This value may be stored at the electronic storage device 64 or elsewhere.

The electronic storage device 64 may comprise software instructions, which when executed, cause the processor 62 to take readings from the timing device 66 to measure the current time or the elapsed time. In exemplary embodiments, the processor 62 may be configured to measure the elapsed time, by way of the timing device 66, from when a first current or voltage measurement is taken and continue monitoring the elapsed time each instance a current or voltage measurement is taken. Once the elapsed time is greater than or equal to a predetermined target time, the processor 62 may be configured to sum the power consumption readings taken during the time period in question and divide the summed total by the number of readings to determine an average power consumption reading for the time period. The processor 62 may be configured to update various power consumption measures as described in greater detail herein. This information can be used to, for example, determine the kilowatt-hours (“kW hours”) consumed by the assembly 10. Alternatively, or in addition, the processor 62 may calculate the elapsed time by multiplying the inverse of the known frequency of measurements by the number of measurements taken.

In exemplary embodiments, at least the following power consumption measures are tracked and periodically updated: monthly power consumption (e.g., accumulated kW hours for the current calendar month); yearly power consumption (e.g., accumulated kW hours for the current calendar year); lifetime power consumption (e.g., accumulated kW hours from time 0 to infinity); last month power consumption (e.g., the accumulated kW hours for the last calendar month); last year power consumption (e.g., the accumulated kW hours for the last calendar year); average monthly power consumption (e.g., average of average hourly or daily power consumption for all hours or days in the previous month); average yearly power consumption (e.g., average of average hourly, daily, or monthly power consumption for all hours, days, or months in the previous month); and monthly averages for the last calendar year. These measurements are merely exemplary and are not intended to be limiting. Any number or type of measurements are contemplated. An exemplary report of power consumption is provided below.

The processor 62 may store these measurements and others from the simulated electric meter 44 in the electronic storage device 64 or elsewhere. The simulated electric meter 44 may be in electronic communication with the network connectivity device 46, which may be in electronic communication with a remote electronic device 52 by way of a network 48. The network 48 may be the internet, cellular network, intranet, or the like. The connection between the network connectivity device 46, the network 48, and the remote electronic device 52 and other components may be wired or wireless. The remote electronic device 52 may be a personal computer, smart phone, tablet or the like and may be configured to receive data from the simulated electric meter 44 and generate a report of power consumption.

The measurements taken from the simulated electric meter 44, such as but not limited to those stored on the electronic storage device 64, may be transmitted to the remote electronic device 52. The processor 62, or the remote electronic device 52, may be configured to track the measurements from the simulated electric meter 44 over a period of time. The processor 62 or the remote electronic device 52 may be further configured to generate a user interface illustrating the measurements from the simulated electric meter 44.

As additionally shown in FIG. 10 , the processor 62, or the remote electronic device 52, may be configured to project, predict, or otherwise estimate future power consumption based on past usage. Such estimation may be accomplished by projecting past usage over a future time period, by determining average usage over a period of time, or the like. It is notable that power consumption may vary significantly by time of the year because, for example, of varying weather conditions. For example, without limitation, warmer or cooler ambient air, the number of sunny days, the intensity of the sun, the amount of cloud cover, and the like may affect illumination requirements, cooling requirements, and the like.

If, for example without limitation, data is available regarding average hourly consumption from the same month of a previous year, the same month's average hourly power consumption may be multiplied by the number of hours in the current month to arrive at a predicted monthly consumption. If such data is not available, then the previous day's average daily power consumption may be multiplied by the number of days in the current month to arrive at a predicted monthly consumption. As a further example, again without limitation, if data is available regarding average hourly power consumption from the previous year, the previous year's average consumption may be multiplied by the number of days in the current year and 24 hours to arrive at the predicted annual consumption. If such data is not available, then the previous day's average daily consumption may be multiplied by the number of days in the current year to arrive at the predicted annual consumption. These measurements and predictions are merely exemplary any not intended to be limiting. Any consumption measurements may be used and multiplied by any time period to determine a predicted consumption measurement for a corresponding time period.

At the end of each month, a monthly consumption measurement may be determined by averaging or accumulating all power consumption measurements tracked during the month. For example, without limitation, all daily power consumption measurements tracked during the month may be summed to arrive at a monthly consumption measurement. As another example, again without limitation, all daily power consumption measurement tracked during the month may be summed and divided by the number of measurements taken to arrive at an average daily consumption measurement for the given month. The same or similar measurements may be taken for other time periods such as hours, weeks, days, or years. For example, without limitation, a yearly consumption may be determined by summing all values tracked during the year, all monthly values tracked during the year, or all daily values tracked during the year. These measurements may be stored as described herein.

The simulated electric meter 44 may be in electrical connection with the electronic components 18 or the additional equipment 42. Some of these components may be configured to track the images being shown on the various electronic display subassemblies 12. For example, without limitation, the processor 62, electronic storage device 64, and timing device 66 may be in electronic communication with the video player 18. As a further example, the additional equipment 42 may comprise a proof of play device configured to track what image(s) are shown on the electronic display subassemblies 12.

Regardless, the processor 62 may be configured to monitor the activity of the video player 18. The processor 62 may be further configured store data on the electronic storage device 64, the electronic components 18, the additional equipment 42, or the remote electronic device 52, indicating what was shown on the electronic display subassemblies 12 at given times, which may be measured by the timing device 66.
